Development of an integrated circuit VLSI used for time measurement and selective read out in the front end electronics of the DIRC for the Babar experience at SLAC

This thesis deals with the design the development and the tests of an integrated circuit VLSI, supplying selective read and time measure for 16 channels. This circuit has been developed for a experiment of particles physics, BABAR, that will take place at SLAC (Stanford Linear Accelerator Center). A first part describes the physical stakes of the experiment, the electronic architecture and the place of the developed circuit in the research program. The second part presents the technical drawings of the circuit, the prototypes leading to the final design and the validity tests. (A.L.B.)
